Cranage LISN Model MS461-100A One Line V-Network (MIL-STD-461E)


General

A line impedance stabilising network (LISN) is used to provide a defined impedance source on each input supply line to the EUT so that measurements of differential and common mode radio noise current can be made. The specified line impedance is conditional on the measurement socket being terminated with a 50W non-inductive resistor and the noise current is measured using a current probe.

Technical Specification

Model MS461-100A LISN is a three terminal device, one terminal earthed, to be series connected between the power source and the primary power input of the EUT. It is a robust, high stability unit which meets the impedance/frequency characteristics specified in MIL-STD-461E (20th August 1999). A shielded input capacitor (8mF) and series resistor (5W) is incorporated for performance and safety reasons. The measurement socket is externally terminated with a high-surge 50W coaxial resistor (also available from Cranage). The case of the LISN is bonded to the ground plane via four M6 screws. An M8 earth stud is also provided for additional earth bonding.
